What are the treatment options for pityriasis alba?

Pityriasis alba is a common, non-contagious skin condition that produces lighter patches with fine dryness or scaling. It is often noticed on the cheeks, around the mouth, or on the arms. The colour difference can look stronger after tanning because nearby skin darkens while the patch does not. It is not the same as a fungal infection, and rubbing or bleaching the area can make irritation more noticeable.

Apply a fragrance-free moisturiser several times through the day, particularly after washing, to soften scale and support the skin barrier. An [Emollient Therapy](/treatments/medical-dermatology/emollient-therapy/) plan may be enough when dryness is the main issue. Use shade, protective clothing, and broad-spectrum sunscreen on exposed skin so contrast is less obvious. If redness, itch, or roughness persists, a clinician may prescribe [Topical Corticosteroids](/treatments/medical-dermatology/topical-corticosteroids/) for carefully limited use. Do not use a steroid cream on a child without advice about its strength, amount, and duration.

Arrange a skin assessment if patches spread quickly, become sharply white, develop marked scale, or do not fit the usual pattern. Seek prompt advice for pain, swelling, oozing, crusting, or significant itch. A clinician can check whether another cause of light or scaly patches needs different treatment.

Could this be pityriasis alba or another cause of pale patches? Which moisturiser is suitable for this skin? If a steroid is needed, where should it be applied and for how long? How should sun protection be adjusted for the affected areas?
